"This Sequential Circuits Pro-One is in amazing condition and fully functional, and is Midi-Capable via INCLUDED Vesta Kozo Midi-CV converter. It is a fully and professionally restored Late-Model with fully-functioning Keyboard. This is all-original, with NO modified circuitry or re-soldered components.
All rotary pots and switches have been professionally cleaned. All key contacts on this later non-J-wire model have been restored and functioning. Everything works and sounds great. While no vintage synth is ever "truly" mint or perfect, this one has been well cared for and not cosmetically re-finished. Incredibly clean unit inside and out. Original Power cord (does not use AC wall adapter).
If you are shopping for this synth, it probably needs no introduction, but obviously it has an amazing sound, midi-syncable programmable arpeggiator and sequencer via CLK input, and incredible-sounding filter, controls, and modulations you would expect from an analogue synth of this era.
This specific model has the coveted "Buddha" circuitboard with interesting and cryptic solder "signatures" inside, including mushrooms,etc.. on the main board, created by the original SC assembly engineers. (see photos). Numbers and markings were made by factory technicians, and I've enclosed photos of those as well.
The late-model keyboard is fully operational and restored with all keys functioning fine, but I have included with the unit the rare and unusual Vesta Kozo MDI-1 midi-to-CV converter so it can be immediately used with any midi-capable or computer/midi sequencer-based system. This unit alone had several hundred in Value, but it's a great match with the synthesizer providing midi capability.
The unit is in excellent condition with virtually no scratches or wear, other than some light wear on the original wooden sides. Case, plastic, knobs are in fantastic condition."
